SU1250333A1 - Apparatus for cleaning internal surface of hollow articles - Google Patents

Description

The invention relates to the cleaning of hollow articles with the help of rotating working elements and can be used in agriculture, transport engineering and other areas of industry for cleaning the inner surface of hollow articles mainly from viscous deposits. “The purpose of the invention is to improve the quality and productivity of cleaning by ensuring reliable removal of contaminants from the scraper as it rotates.

FIG. 1 shows a device for cleaning the inner surface of a hollow article, grab the look; in fig. 2 shows section A-A in FIG. 1 (while rotating the scraper counterclockwise); in fig. 3 - the same, when rotating the scraper clockwise; in fig. 4 — node I in FIG. 1; - in FIG. 5 shows a section B-B in FIG. 2

The device for cleaning the inner surface of the hollow product has a hollow product mounting unit 2 mounted on frame 1, a waste container 4 for removing contaminants, a scraper 5 with reversing drive 6 for rotating and reciprocating and a contaminator 7 for scrubbing 5. Hollow product 3 is fixed in the attachment unit 2 by means of a lever clamp 8, which interacts with the power element 9.

The blades 10 of the scraper 5 are placed with the possibility of divergence in the diametrical plane under the action of the spring 11.

The reciprocating movement is provided by the interaction of the drive shaft 12, made in the form of a lead screw with a nut 13, fixedly mounted on the frame 1.

The wiper 7 from the scraper has a housing 14 in the form of a ring with a conical inner surface mounted on the frame 1 for rotation in the bearing 15. On the co. In the plane of its rotation, the sloping surfaces of the housing 14 are made with slots 16, and in them the knives 17 are installed with the possibility of rotation between the two extreme positions, each of which has two blades 18 and 19.

The device works as follows.

The hollow article 3 is secured in a fastener 1250333 placed on frame 1. .

by means of a lever clamp 8 and a power element 9, for example a pneumatic cylinder. The drive 6 is turned on for the drive shaft 12, which, interacting with the nut 13, receives an axial upward movement.

The blades 10 of the scraper 5 interact with the blades 17, which unfold into one of the extreme positions in which the blades 19 interact with the blades 10, and the blades 18 are removed in the slots 16. The edges of the slots 16, forming a cleaning agent, clean the dirt available on blades x 18 (fig. 2).

The research institutes last rotate in the bearing 15 together with the scraper 5, while the contaminants cleared from the blades 18 are thrown off by the centrifugal force along the tapered inner surface of the housing 14 into the container 4 to discharge the contaminants.

As a result of the axial movement of the scraper 5 relative to the knives 17, the blades 10 are cleaned by the blades 19 on one side and (already cleaned) the internal cavity of the hollow product 3 is inserted, while the blades 10 converge as a result of the interaction with the conical surface of the attachment unit 2, and in the cavity of the workpiece 3, they are pressed to the surface to be treated by means of a spring 11.

A passage upwards along the cavity of the product 3, the scraper 5 cleans its inner surface, while a part of the contaminants is poured into the container 4, and a part sticks to one of the sides of the blades 10.

When the scraper 5 reaches the upper end position, the direction of rotation of the actuator 6 automatically changes and the scraper continues cleaning, the crush is prevented, and the other side of the blades 10 gets dirty. As it moves further down, the blades 10 again interact with the knives 17 , while the knives are turned to another extreme position, in which the blades 19, after cleaning, are removed in the slot 16, and the blades 18 clean the other side of the blades 10.

Thus, in the process of reciprocating vertical transfer

Thus, in the process of reciprocating vertical movement of the scraper with changing the direction of its rotation in the upper extreme position, the dirt from both blades of each knife in the soil remover from the scraper is removed alternately, the dirt from both sides of each blade of the scraper is cleaned hollow inner surface

products and removal of contaminants into the tank for disposal of contaminants.

Ensuring reliable removal of contaminants from the scraper blades during operation during its rotation will improve the quality of cleaning and increase labor productivity.
